The FCRD was founded in April 2005 to lease 32 miles of a former Seaboard Air Line Railroad from CSX. It stretches east from Yulee to Fernandina Beach, Florida and north from Yulee to Seals, with a connection at Yulee to CSX.
The north-south line, formerly the SAL main line before it was abandoned by the combined Seaboard Coast Line Railroad in favor of the ex-Atlantic Coast Line Railroad main line to the west, connects to the St. Marys Railroad at Kingsland. The line is abandoned north of Seals.
